What is transistor & How transistor working

Transistor: Transistor is an electronic device and its  made of semiconductor material. mostly silicon used as a semiconductor material. transistor having many uses. transistor act as  a switch, voltage regulation process, modification of signals, amplification of signals. when N-type  or P-type semiconductor  is connected between two P-type or N- type semiconductor then its look like two PN junction diode….

difference between conductor and insulator

Difference between conductor and insulator

Difference between conductor and insulator: What is conductor: Generally conductor is a material which is allow the current from one place to another place. otherwise we can say the material which is allowing  current flow then that material is called conductor. the some example of conductor is coper, aluminum, silver, gold, etc. What is insulator:…

relay

How to do Relay settings

Relay Settings : here we can see about what is relay and how to do relay settings. Relay is a device used to protect the equipment from damage during the abnormal or faulty conditions. usually relays having two coil supply A1 and A2, two NO and NC contacts, and common supply contacts. working: whenever the coil…

high voltage switchgear

High Voltage Switchgear

High Voltage Switchgear we all are know the electrical voltages are classified into 3 types. low voltage, medium voltage and high voltage. the voltages from 0 to 1000v its called low voltage and voltage from 1000v to 36000v its called medium voltage and above 36000 volt its called high voltage. for handling this high voltage…

medium voltage switchgear

Medium Voltage Switchgear

Medium  Voltage Switchgear: Generally the voltages range from 1KV to 36 KV its called medium voltages. for handling these medium voltages we used medium voltage switchgear. medium voltage switchgear also having the combination of outgoing feeder, control switch , disconnect fuses, auto/remote controls, protection relays, and circuit breakers for protecting safe ON/OFF operations. Mostly  for…
